Description Usage Arguments Details Value Author(s) Examples

butterfly plots all individual waveforms for the condition specified by the stim argument (i.e., a butterfly plot). The grand average waveform is also plotted, using a red line.

1	butterfly(data, electrodes, stim = 1)

`data`	A data frame in the format returned from `load.data`
`electrodes`	A single value or concatenation of several values (to be averaged) indicating which electrodes to include in generating the plot. At this time, if the raw data files imported using `load.data`) do not have a header, you must include a capital "V" in front of the number and enclose each electrode in quotes. (For example, electrodes = "V78", or electrodes = c("V78", "V76").)
`stim`	An integer specifying which condition to plot. Conditions are numbered in the order in which they are imported with `load.data`. The plot title will specify the name of the condition to avoid confusion.

Single electrodes can be passed to the package functions, or several electrodes can be provided (i.e., when using dense arrays) and those electrodes will be averaged together as a single electrode.

A single butterfly plot for the condition specified with stim.
